Gravitational Potential Energy (GPE) = 9.8m/s² (rate of gravity) x 8,000,000kg of water x 50.0m
GPE = 3,294,000,000 Joules (J) which is also the change in GPE
Explanation:
Initially, the object is at rest, u = 0
Acceleration of the object,
(a) Distance travel in 2 second can be calculated using second equation of motion as :
(b) Distance travel in 4 second can be calculated using second equation of motion as :
(c) Initial velocity of the object, u = 4 m/s
(d)
Hence, this is the required solution.
The mass of the box would be 30!
Answer:
The angle between the diagonal and edge = 55 degrees
Explanation:
We will find it by finding the angle between two vectors (a and b)
We will assume it to be a unit cube
Vector a = (1,1,1) (defines the diagonal vector)
Vector b = (1,0,0) (defines the edge vector)
cos (theta) = (a.b)/(|a|*|b|)
theta = 54.74 degrees
theta = 55 degrees (Rounded to the nearest degree)
Answer
Hi,
In a chemical equation, chemicals that react are the reactants, while chemicals that are produced are the products/by products. Both sides of the equation must be balanced.
Explanation
When writing a chemical equation, reactants reacts to produce products. For example in the equation for formation of water, hydrogen combines with oxygen as 2H₂ +O₂→2H₂O where the first part before the arrow represent the reactants and the next part after the arrow are the products. Reactants are on the left where as products are on the right.Coefficient 2, in this cases is used for balancing the equation.
Good luck!
